BALING-PRESS.

Specification of Letters Patent.

Patented Feb. 13, 1912.

To all whom t may concern Be it known that I, JOHN lV. BURKETT, a citizen of the United States of America, residing at Kansas City, in the county of Tyandotte and State of Kansas, have invented certain new and useful Improvements in Ealing-Presses; and I do hereby declare thatl the following is a full, clear, and exactI description of the invention, such as will enable others to make and use t-he same, reference being had to the accompanying drawings, forming a part of this specification.

The objects of the invention are: first, in a continuous power press to control the opening and closing of the feed opening, and secondly to govern the reciprocation of the rack operating the plunger.

rllhe invention consists in the novel construction and combination of parts, such as will be first fully described and then speciiicallypointed out in the claims.

In the drawings: Figure 1. is an isometric view of a baling press, embodying the invention. Fig. 2. is a plan of the same. Fig. 3. is a vertical, sectional view, taken on the lines m, x, on Fig. 2, showing' the positions of the operative parts at the respective ends of the head block movement. Fig. 4. is a transverse, vertical, sectional view, enlarged, taken on the line y, y, on Fig. 2, looking rearwardly. Fig. 5. is an enlarged, isometric view, in detail, of the large sprocket wheel and spur wheels and the supports for t-he shaft carrying said wheels, also showing portions of the upper and lower angle beams adjacent thereto. Fig. 6. is a detail view of portions of the large sprocket wheels and rack bars, the spur wheels and portions of the upper and lower beams showing operative positions of the rack bars. Fig. 7. is a detail view, in perspective, of the head block and rack bars.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

lVith reference particularly to the drawings, the bed of the baling press consists of the angle beams 10, 10, which are arranged in a parallel position and the requisite distance apart for the formation of the bale. These beams extend the full length of the press, and have the grooves formed by the angles of the beams facing inwardly.

lVith the lower surface and forward ends of the beams 10, are connected the ends of a transverse supporting plate 12, which is bent between said ends in a downwardly-curved line, and bears upon the upper surface of the forward axle 14. Through the plate 12 and the axle extends the king bolt 15. Upon the ends of the axle are mounted the forward wheels 16.

At a point distant from the forward axle 14, rearwardly and approximately twothirds the distance toward the rear ends of beams 10, is positioned the rear axle 17, which is bolted transversely to the lower surface of said beams. Upon the ends of said axle are the wheels 18, which are slightly larger in circumference than the forward wheels 16. Above the beams 10 are the longitudinally-extended angle beams 20, the grooves formed by the angles or surfaces of the beams facing outwardly, the downwardly-extending portion of the beams 20 being in vertical lines with the upwardlyextending portions of angle beams 10. These beams 2O are parallel with the beams 10, and at an approximate distance in height from the beam 10 to the distance allotted between said beams 10, and extend in length from a point in a vert-ical line with the rear ends of beams 10, to a point in the direction of the forward ends of beams 10 approximately two-thirds the length of said beams.

rl`he upper beams are secured in a horizontal position by the vertical side plates 21, which form the sides to the baling cha1nber 21X, and are bolted to the inner surfaces of the upwardly-extended portions of angle beams 10, and the outer surfaces of the downwardly-extending portions of beams 20. These plates 21 extend from a point about two-thirds the distance forwardly of the rear ends of beams 10, the proper distance to afford a large feed-opening 210, or to a point nearly intermediate the ends of beams 10, the space between the rear ends of beams 10 and 20, in rear of the feed chamber constituting the baling chamber 20X. The bottom of the feed and baling chambers consists of a wide plate 22, extending from the line of the forward ends of the plates 2l, and from the inner surface of one plate 21, to the innerl surface of the opposite plate 21, and also in length to a point in line with the rear ends of beams 10.

23 indicates the top to the baling chamber, which consists of a plate extending in width from the vertical line of the outer edge of one of the horizontal portions of the angle beams 20, to a like point on the other angle beam 20, and in length from a point in a vertical line with the rear ends of beams 20, to a point a short distance forwardly of the vertical lines of the rear ends of the side plates 21, to the feed chamber 21".

Within the baling chamber is a rocking plunger or head block 24, for compressing the material to be baled. The head block consists of a hollow casting, the sides 24X, of which are in vertical lines with and a slight distance from the vertical, inner surfaces of the sides 2l, of the feed chamber. rI`he top 24, of the casting or head block is inclined rearwardly and downwardly, and is connected integrally with the sides 24X, and the vertical plates 25, which constitutes the compression face of the head block. The head block is mounted on the wheels 26, the journals 27 for which are secured to the inner surfaces and lower, forward portions of the sides 24X, which portions of the sides are slightly inclined upwardly and forwardly to the line of the face 25, so that in a movement rearwardly of the head block the lower surface of the face 25 comes into a close position with the upper surface of the plate 22, in the bottom of the feed chamber, and the forward portion of the inclined top 24 approaches quite closely to the line of the lower surface of the forward end of the top-plate 23, which is as seen the rear end of the feed opening 210, in its reciprocating movements. In the outer surfaces of the sides 24X, of the head block, at points about equi-distant from the rearportion of the top-plate 24, and thejournals 27, for the wheels 26, are horizontal recesses 28, in which are seated the rear ends of the flat rack bars 30, these bars being secured in the recesses by means of the bolts 29, eX- tending through said bars, and the sides 24X, of the head block (see Fig. 7). Upon the outer surfaces of these bars adjacent to their forward ends, are rigidly secured the stop pins 31.

At a point a short distance forward of the line of the forward ends of the sideplates 21, to the feed chamber are the rearwardl curved guide plates 32, arranged in a vertical position and in the path of movement of the studs 31, on the rack bars 30, these guide plates 32 being positioned in such a manner that when the head block is in a position at the rear end of the feed chamber and at the end of the head block movement for compressing the baling material in the baling chamber the studs 31, on the rack bars 30, are in contact with the curved guide plates 32. These guide plates are secured at their upper ends to the lower surfaces of outwardly-extended portions of angle beams ,20, and at their lower ends to the outer surfaces of the upwardly-extended portions of the beams l0.

With the upper surfaces of the inwardlyextended portions of the angle beams 10, at a point in a vertical line with the forward ends of the angle beams 20, are rigidly connected by the bolts 33X, the forwardly curved guide plate 33, the upper end of which plate is secured rigidly by the bolts 33o to the upper surface of a transverse cleat 34, secured at its ends to the upper surfaces and forward ends of beams 20. These guide plates 33 are in the path of the forwardends of the rack bars 30, and come into contact therewith at the end of their forward head block movement. In the upwardlyextended portions of the angle` beams 10, transversely to the point of attachment of the lower ends of guide plates 33, is a groove 10, of the proper depth and length, in which the stop pins 3l, on the forward ends of the rack bars 30, enter in the beginning of a rearward movement of the head block.

To the lower surfaces of the angle beams 20, intermediate vertical lines extending through the forward ends of the sides 21, of the baling chamber and the forward ends of beams 20, is secured rigidly the outer ends of the short horizontal studs 35, which are spaced apart a short distance from each other.

To the inner surfaces of the upwardly-ex- I tended portions of the beams 10, in a vertical line with the studs 35, are connected rigidly the outer ends of the short, horizontally-extended lugs 36. The inner ends of these lugs 35 and 36 are connected, respectively, with the outer surfaces and upper ends of the parallel shaft-bearing plates 37, which are spaced apart a short distance from each other. In the said plates, at a point equi-distant from their upper and lower ends and from vertical lines extending through the said plate at the point of connection of the lugs 35 and 36 is journaled a transverse rotary shaft 37X, the ends Lolaizaal mounted the spur wheels 40. The ends of plates 37, extend both forwardly and rearwardly of the main portion of the plates, such end having its upper and lower surfaces inclined toward a point horizontally in line with and bisecting the axis of shaft 37", the plates being'in the form of a diamond. Vith the outer ends of these plates are connected the bolts 37 o.

Wit-h the outer surfaces of the plates 37,

ing in the path of the rack bars in their highest plane of movement, and with the lower portions of said plates 37 are rigidly connected the inner ends of the studs 47X, upon the outer ends of which studs are journaled the lower guide rollers 47, these roll ers being positioned in a vertical line with the rollers 46, and in the path of the rack bars 30, in their lowest plane of movement. Upon the inner surfaces of the rack bars 30 are secured a series of studs 41, beginning at a point adjacent to the forward ends of the rack bars a distance corresponding to the position of stud 31, and in regular order in the direction of the rear ends of said bars, these studs being of the requisite number, spaced apart a distance corresponding to the width of the teeth or spurs of the spur wheels 40, and in number suiiicient to carry the rack bars to a position in which the forward ends of the bars come into contact with the upper portion of the forward, curved guide-plate 33, in which position of the rack bars 30, the last stud in the direction of the rear ends of the rack bars is engaged by the spur wheels,i to move said studs in an arc of a circle, while the forward ends of the rack bars are moving in the arc of a circle in contact with the guide plate 33, downwardly to a position shown in dotted lines in Fig. 3, in contact with the lower guide rollers 47, and moving rearwardly to move the head block in a corresponding direct-ion.

The number of studs 41, shown on the inner surface of the rack bars are seven, and the spurs on the spur wheels are live in number, which number may be varied as the condition requires. These studs 41 extend to a position about one-half the distance from the forward toward the rear ends of said rack bars, and with the spur wheels Aand guides act as a'mangle rack to communicate a reciprocating movement to the head block.

Upon the upper, horizontal surfaces of rthe inwardly-extended portions of the angle beams l0, at points a short distance forwardly of the guide plates 33, are secured the journal boxes 48, in which is journaled a transverse, rotary power shaft 49, upon which shaft, intermediate the journal boxes .is ixedly mounted the small sprocket wheel 50. Over this sprocket wheel extends an endless sprocket chain 51, which also ex- ;tends to and over the large sprocket wheel 38, on shaft 37X.

The end of shaft 49, on the left-hand side of the machine, extends a short distance outwardly from the line of theoouter sur-V face of the journal boxes 48, and upon said tions of the angle beams 10. The rear por- 4tion of the base extends forwardly to within 'a short distance of the journal boxes 48, Vand upon the rear, upper, horizontal surfaces of the base is journaled in the journal :boxes 56, a transverse,rotary power shaft 57. The end of said shaft on the right and left-hand side of the baling press extends a short distance beyond the line of the journal boxes, and upon said end of the shaft are mounted the large balance wheels 58.

-Upon the said shaft 57, in line with the gear wheel 52, is a small gear wheel 60,k

'requiring illustration or further description,

other power being employed when found convenient to the operation of the press.

The automatic feeder for feeding the baling material through the feed-opening 21O into the feed-chamber 21X consists of a rocking beam, of considerable length, which is secured by the clamping rods 66, to the flanges 67X, on the upper portion or angle' of a triangular plate 67 which plate is secured rigidly at the apex to a rock shaft 68. The shaft 68 is journaled at its ends in the arch plates 69, on the upper ends of the rods or standards 69, 69X, these rods on the respective sides of the baling press being in` end of the shaft is mounted a large gear 1 other.

pairs and spaced apart at an angle to each The forward standards or rods 69o at their lower end are bent at right angles and flattened, and bear on the upper surfaces of the cleats 34, and are secured by the bolts 34X, which pass through the flattened lower ends of the rods 69o, the outer ends of the cleats 34, and the horizontal portion of beams 20. The rods 69X are also flattened at their lower ends, and secured by bolts 70 to the upper surfaces of the horizontal portions of the angle beams 20, at a point a short distance in rear of the vertical lines passing through the forward ends o the sides 21, of the baling chamber.

The upper end of the beam 65 extends in its normal position upwardly and rearwardly to its full elevation above and in a vertical line with the rear portion of the baling chamber, and upon the forward surface of said end are lugs 65X.

vided with lugs 7 2, on its inner surface and upper end pivotally connected with the lugs 65X, on the rocking beam 65. At a point 0n the arm 71, a short distance below the lugs 72, is a transverse bolt 73, wit-h the ends of which bolt are connected pivotally the upper ends of the lrods 74, which hold the arm 71 normally at an acute angle to the beam 65, and directed toward a line extending vertically through the central portion of the feed chamber, the lower ends of the rods being pivotally connected with the rear surfaces of the arch plates 69.

Upon the forward surface and lower end 'of the feed arm 71 is rigidly connected a block 75. Upon the outer surfaces and lower ends of the arm 71 and block 75 are flat feedplates 76, upon the lower end portions of which plates are teeth 77, for drawing upon the baling material.

As heretofore described, the feeder is of well-known construction, and isI employed in feeding the material to the ordinary baling press.

80 indicates the apron for prevent-ing the baling material from entering the feed chamber behind the head block, when moving rearwardly to compress 4the material. This apron consists of a rigid material, such as metal plate of nearly the same width as the space between the sides 24X, of the head block, and in length is about equal to theY length of the sides 21, of the feed chamber.

Through the sides 24X, of the head block,

`near the inner surface of the top 24, is a transverse rod 81, around which rod is extended the rear end of apron 80. The guides of t-he apron 80 consist of channel bars 82, connected rigidly to supports 82X secured to the angle beams 20, said channel beams being adjacent to the innerv surfaces of the with the forward ends of the sides 21, of the g feed chamber, the grooves 83 being opposite each other.

Upon the ends of a transverse rod 84, are rollers 85, loosely mounted thereon, and

which rollers have a sliding bearing on the ylower surfaces of the respective grooves 83. Around the rod 84, between the rollers are extended portions of the forward end of the Aapron 80, which telescope within the guides 83. Vith the ends of rod 84, between the apron and the rollers is pivotally connected the lower forked end of the timing lever arm 86, the upper end of which arm is forked and extended inwardly and pivotally con- 'nected with the ends of the bolt 87, extend- `ing through the lower portion and end of :the triangular plate 67.

71 indicates the feeding arm, which is proi Upon the upper surfaces of the horizontal Iportions of the beams 20 are transverse ,boards 88, extending over the feed chamber ,upper edges of these boards, which are set- -edgewise in position, is connected a frame ,or table 90, having a centrally-located, rectangular opening 91, of the same width as ythe feed-opening 21, to the feed chamber 21X. Vith the inner, longitudinal sides to -the opening 91, are connected the downwardly-extended plates 92.

Upon the upper surface of the frame 90,

on the left-hand side of t-he machine, is an 'upwardly-extended, material-guiding plate 93, having a lower, flanged portion 94, secured to the upper surface of the frame 90 .and extending nearly the length of said frame. The plate 93 extends upwardly a considerable distance, and upon the forward end of the frame is a vertical, transverse `plate 95, the same height as the plate 93,

and which is provided with a flange 96, secured to the upper surface of frame 90, the two plates being connected at their adjacent ends. In the forward, transverse vplate 95 are slots 97, which permit the rods 74 on the feeder arm 71 to enter inthe rocking movement of the beam 65.

To the upper surfacecf frame 90, a short distance from the inner surface of the plate 93, are connected rigidly the lower ends of the rack teeth or rods 98, which are arranged a short distance apart in a'parallel plane with plate 93, to form a rack, and extend upwardly a slight distance above the plane of the upper portion of said plate 93, which forms a back to the rack teeth.` The teeth or rods set out from the plate 93about onehalf the length of the teeth of an ordinary hay fork. 99 indicates a block, at the forward ends of the opening 91, in the frame 90, secured to the inner surface of plate 95, and extending downwardly as far as the plate 92, thus serving to direct the baling material into the opening in the baling chamber. The upper surface of the block 99 is inclined downwardly and rearwardly, for assisting the passage of the baling material.

100 indicates the dumping frame for thel division boards, which is hinged to the rear end of the opening 91, in the frame 90, and is provided with the handles 101, for raising the frame 100. rIhe frame 100 is of well-- known construction, and enables the deposit of the division board without danger to the operator of the press. The tension device at the rear end of the baling chamber, which is also of well-known construction, consists of the rod 102, passing beneath the beams 10, and upwardly through the outwardlyextended portions of beams 20, and the ends of the plate 103, the ends of the rod being screw-threaded. The tension is obtained by the adjustment of the wheels 104 whose hubs are screw-threaded and engage the screwthreaded ends of rod 102.

In operation, power from the engine transmitted from the plunger rod 64, to the crank shaft 57, thence from the small gear 60, on said shaft, to the large gear wheel 52, on shaft 49, thence from the sprocket wheel 50, on said shaft to the sprocket chain 51, thence from the sprocket chain to the large sprocket wheel 38, on shaft 37, and from the spur gear wheels 40, on said shaft, to the rack bars 30, operating the head block 24, and a reciprocating movement is imparted to the head block 24. In these reciprocating movements of the head block the studs 41, on the rack bars are constantly in engagement with the spur wheels 40, and in moving rearwardly the rack bars are guided by the lower rollers 47, to a point in which the head block reaches the end of the inward movement, at which point the stop pins 31, on the outer surface and forward ends of the rack bars, come into contactl with the lower portion of the guiding plate 33, and in continuance with the movement of the spur wheels the studs are caused to move on said curved surface upwardly, the last stud 41, on the forward ends of the rack bars, being at the same time in engagement with and between the spurs of the wheels. In this movement the forward ends of the rack bars are raised in an inclined position, and broughtinto contactwith the upper guide wheels 46, and consequently rocking the head block on its wheels 26, and bringing the face portion from its inclined position,

as seen in Fig. 3, into a perpendicular position, and the lower portion of the face portion 25. In the forward movement of the rack bars in contact with the guide rollers 46, the ends of the rack bars come into contact with the upper portion of the curved guide plate 33, at which moment the last studs 41, in the series on the rack bars are within the spurs of the spur wheel 40, and consequently the rack bars move downwardly, guided by the curved surface of the guide plate 33, when the rack bars come into position upon the lower guide rollers 47, and the spur wheels engage with each one of the studs 41, on the rack bars, and the head block 24 moves rearwardly, this operation being repeated, and as rapidly as the power is applied. rIhe constant supply of the baling material to the feed chamber 21X is made during the reciprocation of the head block 24, and at the time subsequent to the completion of its rearward movement to compress the material within the baling chamber, and a movement of the head block toward the forward end of the feed chamber, approximately one-half the distance toward the forward end of the feed chamber, or during the movement of the timing lever arms 86, from their rearwardly-inclined position, as seen in Fig. 1, to a forwardly-inclined position seen in dotted lines in Fig. 3, in which the roller 84 has moved about one-half the distance in the direction of the forward end of the channel guide-plates SQ and the feeder beam obtains a dwellsuiiicient in length of time to enable the feeding of the baling material within the feed opening. At the incipiency of this movement of the head block the beam 65 is given an upward movement, in a slight degree, and upon the change of position of the arms S6, in which the dwell of the beam 65 takes place, the said beam 65 moves downwardly a like distance. During this time in which the head block is complet-ing its iorward movement, described, the bundle of baling material raised by the hand fork is thrown upon the table 90 and the bundle falls across the opening 91, and as the head block moves forwardly, the power of the yhead block is transmitted through the apron 80, to the pivoted lever arms 86, which now act first to produce a dwell of the feeder beam as before described and then to draw upon the plate 67 and beam 65, and as apron 80 moves within the guides 83, the feeding arm 71 moves downwardly with a quick movement, into the feed chamber of the baling press, the teeth 77 drawing the material into the feed chamber, in rear of the head block. The head block 24 having reached the end of its forward movement and begun its rear ward movement, the apron 80 acts upon the lever arms 86, and the beam 65, as before described, in changing their operative positions, and as the head block 24 moves rearwardly in the baling chamber it compresses the material, the apron closes the space in the feed chamber behind the head block, and thus prevents admission of the material. The charges orA bundles of material are repeatedly delivered to the feed chamber, as usual in baling, until the baling chamber contains an amount equivalent to form a bale, and upon the return movement of the head block, a division board (not shown) is placed upon the dumping board 100, and dropped into the baling chamber in the usual manner.

In pitching the material to be baled across the opening 91, in the table 90, the rack 98 acts as a guide to the bundles, and at. the same time the tines of the fork which compress the material against the Wires 98, are enabled to be quickly withdrawn from the bundles as the tines are given s/pace in which to project, in rear of the wires 98, the plate 93 holding in check any material passing said wires. The rapid movement of the head block obviously requires the material to be supplied with considerable speed, the head block in each forward movement removing any loose material accidentally falling into the feed chamber in its rearward movement, and this is discharged from the forward end of the baling chamber. The resistance to the compression of the material in the baling chamber is controlled by the usual compression devices 102 and 103.

I am aware that mangle racks have been employed in baling presses to actuate the plunger. In my construction the rack bars are rigidly connected with the plunger and the reversals of movement are made conjointly with the rocking movement of the plunger while the reciprocating movement of the rack is completed between opposed curved guide plates with which the stop pins on the rack bars and the ends of the bars alternately come into contact.

Various changes in the construction of the invention may be made, within the scope of the appended claims, without departing from the spirit of the invention.
